I have just finished fitting a lcd to my frankenstien, Just ordered a rasberry pi, i now need to build the cable. I am glad i held off purchasing a new dmd. Approx $500 here in Oz.
The pi has a 26pin connector so i gather you dont need to use the larger cable that is in your pics.
So really i could go from 14 to 26. I am luck enough to have a 3d printer so i would like to make a cover that fits over the resistors. Do you have a wiring diagram with the pin numbers. I could work it out off the pics if i had to thanks in advance.
One other thing, can this cable be used on sam, sega and williams or are they wired differently.

Thanks for the info i have made some stern plug and play adaptors for adding extra leds to flashers.
I was going to use the same concept for the cable adaptor.2014-04-10 23.12.32 (Medium).jpg
I also have a pic of the mounting brackets i have printed for the lcd.2014-04-10 23.06.18 (Medium) (2).jpg
I have read people have been able to use hdmi to vga on the dmd extenders. (If this does not work it could be a problem)

Hi all here is a pic of the resistor adaptor i made, I am ordering a dmd extender to compare both, one issue for me is the boot time, it is taking over 10 seconds for the pi to load.
Boot time as per videos with the dmd extender almost seem to be instant.

I have followed the instructions and finally have smart dmd working, it took me a while to get my usb wifi to work and i have mapped the drive, the question i have is when using pinball browser i selected the smartdmd file from the mapped drive. When i make changes it says access is denied, I also noticed when i tried to copy files to the mapped drive it would not allow me, it seems to be read only, is this a setting in the network configuration on the pi.

Yes those lines are there.

it also has underneath
[update]
comment = update
path = /boot
read only = no
public = yes

Yes i did the pre configured distrib, i couldnt get wifi to work, i eventually worked out how to get wifi to work and did an update step 11 probably where i went wrong, when you say smbpasswd -a root and use the same password (than) for root is that the same password, i am stumped at (than) is that supposed to be the same as root.
which is what i used.
I am sorry i have no experience with the pi and it boots directly into smart dmd not sure how to exit back to log in.

will reinstall, i beleive there is a problem with card, i am unable to write or edit at all like it is locked.

Ok i have started from scratch, install pre-configured distribution onto flash drive.
All works fine, I can see smartdmd under network in w7.
I can map network drive.
I cannot copy files over to this drive. (destination folder access denied) you need permission to perform this action)
I try and change security but it does not allow, i have played with network settings no luck, I can see the workgroup is called workgroup but windows 7 wants to give me a homegroup password.
I think the problem is with w7 i will keep trying a few things.
I did check the [smartdmd] settings correct.
Thanks for your help

Ok Seems to be working finally, reset password in smb and seem to be working.
